概括

结合放射治疗与抗增殖性亚胺二- (AID-1-T) 药物,显著降低了高度质瘤细胞的增殖和迁移. 这种组合疗法抵消了辐射诱导的前迁移效应,为治疗侵略性脑瘤提供了一种有前途的方法.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
放射治疗研究放射治疗研究

背景情况:

高度质瘤表现出对治疗的耐药性和侵略性的复发.
放射治疗虽然是标准的,但可以促进瘤细胞迁移和复发.
抗增殖性阿帕特马是潜在的治疗药物,但它们与辐射的联合使用需要调查.

研究的目的:

评估电离辐射对人类质瘤细胞活力和迁移的影响.
为了评估电离辐射和aptamer bi-(AID-1-T) 的组合.
为了确定aptamer是否增强了放射治疗的疗效,并减轻了辐射诱导的迁移.

主要方法:

使用了原发性和复发性人类质瘤的细胞培养物.
治疗包括电离辐射 (20 Gy) 和双AID-1-T) 体 (10 μM).
测试包括MTS,Transwell,免疫细胞化学和转录组分析.

主要成果:

电离辐射对扩散产生了差异性的影响 (在初级质瘤中减少,在复发性质瘤中增加) 以及在两者中增加的迁移.
组合疗法显示出协同效应,显著减少了增殖和迁移.
该组合抑制了辐射诱导的迁移增强和改变基因表达,减少了亲繁殖/迁移基因,增加了反迁移/亲亡基因.

结论:

电离辐射和bi-(AID-1-T) 胺体的组合有效地减少了质瘤细胞的增殖和迁移.
这种协同方法可以抵消辐射诱导的迁移效应.
对存活细胞进行进一步的研究是有必要的,以充分了解治疗的影响.

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
